A general spectral nonlinear elastic consistent tangent modulus tensor formula for finite element software

open access: yesResults in Applied Mathematics, 2020
The consistent tangent modulus tensor requires the formulae for the derivatives, with respect to the right Cauchy–Green tensor, of invariants that described the invariant-based potential function.

Elastoplastic analysis by return-mapping method with rigorous loading criterion for extended subloading surface model

open access: yesNihon Kikai Gakkai ronbunshu, 2019
The extended subloading surface model is capable of describing cyclic loading behavior accurately. The elastoplastic deformation analysis by the finite element analysis can be executed efficiently by the complete implicit stress integration method with ...

Elastoplastic deformation analysis by return-mapping and consistent tangent modulus tensor based on subloading surface model (1st Report, Formulation of return-mapping)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The subloading surface model possesses the automatic controlling function to pull back the stress to the yield surface. However, this function is not concerned with the subyield state, i.e.

Elastoplastic deformation analysis by return-mapping and consistent tangent modulus tensor based on subloading surface model (2st Report, Deformation analyses of machine elements)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The implicit stress integration algorithm was devised in the first report by formulating the return-mapping based on the cutting-plane projection and the consistent tangent modulus tensor due to the numerical method for the subloading surface model.

Constitutive modeling of two phase materials using the Mean Field method for homogenization [PDF]

open access: yes, 2010
A Mean-Field homogenization framework for constitutive modeling of materials involving two distinct elastic-plastic phases is presented. With this approach it is possible to compute the macroscopic mechanical behavior of this type of materials based on ...

An exact consistent tangent stiffness matrix for a second-gradient model for porous plastic solids: Derivation and assessment [PDF]

open access: yesMathematics and mechanics of solids, 2022
It is well known that the use of a consistent tangent stiffness matrix is critical to obtain quadratic convergence of the global Newton iterations in the finite-element simulations of problems involving elasto-plastic deformation of metals, especially ...

Strain localization analysis using a multiscale model [PDF]

open access: yes, 2007
In order to analyze the formability of steels in sheet metal forming, a ductility loss criterion is coupled with a multiscale model. The behavior at the mesoscopic (grain) scale is modeled by a large strain micromechanical constitutive law, which is then
